Pyrometallurgical Process an overview | ScienceDirect Topics
The pyrometallurgical process serves for the generation of cast vanadium concentrate (CVC) from which high purity vanadium chemicals are extracted. At SCR, spent metal catalysts and metal residues containing Ni, Co, Mo, V, and W are processed to reclaim the metals. Process details are not available for this plant [697].
